How many people can attend a LiveShare session?

We are disabling LiveShare in mid-January 2018. Please see our announcement for the full details.

There are no known limits on the number of attendees that can view a LiveShare session, but there is a limit of 40 attendees on the voice conference associated with the LiveShare. If you need a larger voice conference, you can still use LiveShare, but you'll need to use another teleconference solution for the audio.
